摘要
厌氧氨氧化是处理污水中氨氮和亚硝酸盐氮的最有效技术之一,但在实际应用中低生长速率和对环境因素的敏感性使得厌氧氨氧化过程多变且不稳定.而动力学模型的研究可以为更好地理解和使用脱氮技术提供有价值的工具,该文对厌氧氨氧化抑制、恢复和过程动力学模型进行了综述,阐明修正的Boltzmann模型广泛应用于厌氧氨氧化抑制后恢复性能的描述,并深入探讨不同反应器的动力学过程,认为修正的Stover-Kincannon和Grau二阶模型是最适合不同厌氧氨氧化反应器过程动力学模型,研究结果对厌氧氨氧化工艺环境因素的调控和反应器的优化设计具有一定的指导意义.
Abstract
Anaerobic ammonia oxidation(anammox)is one of the most efficient techniques to dispose of sewage ammonia nitrogen and nitrite nitrogen within a reactor.However,in wastewater treatment,anammox bacteria are low growth rate and sensitivity to environmental factors that make the reaction conditions are variable and unstable.In this way,the study of the ki-netics and modeling can be a valuable tool to better understand and use deammonification technology more efficiently.In this paper,the inhibition,recovery and process kinetics models of anammox were reviewed,and the modified Boltzmann mod-el was widely used to describe the recovery performance of anammox after inhibition,and the kinetic processes of different anammox reactors was deeply discussed,it was considered that the Grau second-order model and modified Stover-Kincannon model were the most appropriate and shareable reactor-kinetic models for different anammox configurations.This review plays an important role in environmental factors regulation and the optimization design of anammox reactor.
